The following is a brief overview.

• ISBN-13 is now fully supported by OCLC for both the Connexion browser and Connexion client 1.60. Also, in order to accommodate the ongoing growth of the WorldCat database, OCLC is changing the format of the 001 in OCLC MARC bibliographic records starting with OCLC record number 100 million to the new 9-digit numbering system. Starting with OCLC record number 100000000, the prefix will be ocn, the number will be 9 digits in length, and there will be no trailing space.
• Other changes impacting the Connexion browser include:
  • Enhancements to metadata extraction and creation.
  • Changes in bibliographic format for metadata extracted from files in an .htm or .html format.
  • "Standardized" notes and 007 field automatically supplied for records created via metadata extraction.
  • Guided entry for fields 541 and 583 for archival materials.
  • Authority history for LC Names and Subjects.
  • Changes to controlling headings, and more.

• Changes to the Connexion client 1.60 are automatically available to the user. Until the implementation of Client 1.70, records exported from Connexion client 1.60 do not include the OCLC control number in the 035 field. A short list of changes includes:
• The ability to extract metadata for MP3 files.
• The requirement to use the same double dagger subfield delimiter in the Control Headings window as is used in records and other windows in client.
• Full mode users now can control more headings in bibliographic records.
• Problems in the process of controlling headings have been resolved.
• Among other enhancements, CatExpress users will find changes to the French interface, the ability to choose fields to delete from bibliographic records that are expired from CatExpress and the inclusion of the 035 field in records being exported.
